To all whom it may concern.-

Be it known that I, GEORGE EDGAR, J un., a subject of the King of GreatBritain, residing at the Tredegar Dry Docks and Wharf Company Limited,Newport, county-of Monmouth, England, have invented new and usefulImprovements in Gearing, of which the following is a specification.

This invention relates to a transmitting mechanism for distributingmotive power to any one or more of a number of rotating shafts fordrilling purposes and for other purposes requiring a correspondingeffort, speed of rotation, and facility for starting and stopping theoperation.

The contrivance is specially adapted as a central station from which anydesired number of leads can be taken through flexible shafts toperformoperations at many points at the same time on a structure the size ofwhich prevents it from being readily moved. The operations to beperformed are suchv as can be effected by a rotating element, theposition of which can be varied as desired and comprise the dressing ofcastings by emery grinding-wheels and the application of revolving wirebrushes, as well as drilling holes.

The contrivance has a sufficient degree of portability to enable it'tobe shiftedfrom place to place where the work is required to be done.

The accompanying drawings show a form of construction of mechanismsuitable for effecting the purposes above'described.

In the drawings, Figure 1 is'a plan. Fig. 2 is a side elevation. Fig. 3is a sectional end elevation'taken' along the line 3 3 of Figs. 1 and 2.Fig. 4 is an end view of a detached bracket shown on the right of Figs.1 and 2; and Fig. 5 is a sectional end elevation of a portioncorresponding to Fig. 3, but with an alternative construction of clutch.

In the views, a; is a shaft which is rotated by some agency, such as amotor, electric or otherwise, specially devoted to the purpose or whichis driven from a general source of motive power by a belt and pulley orsome equivalent organ. This shaft extends continuously in the directionof the length of the machine along the middle and is supported in twobearings, (marked 6 12.) From this main or primary driving-shaft poweris transmitted laterally to secondary shafts c c, of which four 1 areshown, though the number can be indefinitely increased. For each pair ofsecondary shafts a bevel-wheel d is secured to the primary shaft a, andmounted to rotate freely on each shaft 0 0 is a bevel-wheel e, whichcontinuously gears with one of the bevel-wheels d.

Slidably'mounted on each secondary-shaft, with a feather-key connectionor its equivalent, is a clutch-piece f, and means are provided forputting it into and out of connection with facilitywith a correspondingclutch element formed on the rear face of each of the bevel-wheels e.

It will be observed that the nature of the gearing is such thatrelatively to the person who is operating the drilling, grinding, orother tool the rotation of all the secondary shafts will be in the samedirectionthat is to say, for example, all clockwise when the primaryshaft at the right-hand end is driven clockwise.

In Figs. 1, 2, and 3 a positive clutchof the jaw or toothed type isshown,and in Fig. 5 there is an alternative construction in which theconnection is made in a less abrupt manner by friction-cones.

mounted in bearings carried in pedestals g, and to support the innerends a pedestal h is provided, situated between two bevel-wheels e e andso constructed as not to interfere with the continuity of the shaft a.The whole is carried on a bed-plate a, having feet 1', whereby it can besecured to foundations or to a frame'or other bed-plate. Also endflanges in are provided for the purpose of making connection with thebed-plate of a motor or other actuating organ. On one bed-plate Thesecondary shafts at the outer ends are more than two pairs of secondaryshafts may be mounted, or, alternatively, provision for a larger numberof secondary shafts may be getherby the-end flanges.

In the figures, by way of example, a method of utilizing the rotatingfree end of the primary shaft a is shown. It consists of an arrangementfor grinding the tools employed in the machine or others and comprises awheel 0%, secured to the shaft a, and rest at, slidably mounted -in abracketo, secured to the bed-plate a. I

In Fig. 5 is shown a device for the forced application of the slidingelement f of the friction-clutch and for maintaining it in gear,comprising a forked bell-cranklever p 19 the horizontal arm 19 of whichcarries ,a pivoted nut. A screw mounted in the pedestal y, can by meansof the small hand-wheel r be so operated as to effect the connection anddisconnection of the friction-clutch.

In Fig. 3 a flexible shaft 8 is shown coupled to one of the secondaryshafts c and arranged to drive an emery-wheel t.

I claim- 1. A transmitting mechanism adapted to facilitate thedistribution of motive power from a central station the position ofwhich is adapted to be shifted, comprising a bed-plate, a primarymotion-shaft mounted in bearings carried on the bed-plate, secondaryshafts adapted to gear in pairs with the primary shaft, and a clutchadapted to connect or disconnect each secondary shaft.

2. A transmitting mechanism adapted to facilitate the distribution ofmotive power from a central station the position of which is adapted tobe shifted, comprising a bed-plate, a primary motion-shaft mounted inbearings carried on the bed-plate, secondary shafts, a loose bevel-wheelon each secondary shaft, a bevel-wheel keyed to the primary shaftengaging with a pair of the loose bevel-wheels and a clutch adapted toconnect or disconnect each secondary shaft.

3. A transmitting mechanism adapted to facilitate the distribution ofmotive power from a central station the position of which is adapted tobe shifted, comprising a bed-plate, a primary motion-shaft mounted inbearings carried on the bed-plate secondary shafts mounted intransversely situated bearings pedestals carrying said bearings the endsof the secondary shaft-s toward each other being carried by a pedestalcommon to the two and intersected by the primary shaft, a loosebevel-wheel on each secondary shaft a bevel- Wheel keyed on the primaryshaft and engaging With a pair of loose bevel-wheels and a clutchadapted to connect or disconnect each secondary shaft.

L. Atransmitting mechanism adapted to fa.- cilitate the distribution ofmotive power from a central station the position of which is adapted tobe shifted, comprising a bed-plate, a primary motion-shaft mounted inbearings carried on the bed plate, secondary shafts adapted to gear inpairs with the primary shaft, means for rotating the primary shaft and afriction-clutch adapted to connect or disconnect each secondary shaft.

5. A transmitting mechanism adapted to facilitate the distribution ofmotive power from a central station the position of which is adapted tobe shifted, comprising a bed-plate, a primary motion-shaft mounted inbearings carried on the bed -plate secondary shafts mounted intransversely situated bearings pedestals for said bearings the ends ofthe secondary shafts toward each other being carried by a pedestalcommon to the two and intersected by the primary shaft, a loosebevelwheel on each secondary shaft a bevel-wheel keyed to the primaryshaft, and meshing with said bevel-wheels, and a friction-e1 utchadapted to connect or disconnect each secondary shaft.

6. Atransmitting meehanisn'i adapted to facilitate the distribution ofmotive power from a central station the position of which is adapted tobe shifted, comprising a bed-plate, a primary motion-shaft mounted inbearings carried on the bed-plate, secondary shafts adapted to gear inpairs with the primary shaft, and a clutch adapted to connect ordisconnect each secondary shaft.

In testimony whereofl have signed my name to this specification in thepresence of two sui scribing witnesses.
